Huawei energy arm matches Tesla, exposing Europe's green tech blind spot
Huawei’s unheralded energy division has quietly grown to rival Tesla’s storage business, illustrating how Chinese firms are capturing the strategic infrastructure of the global energy transition.
Huawei Digital Power generated 68.7 billion yuan in revenue in 2025, a 24.4% increase from the previous year. This performance puts the unit, which manufactures solar inverters, battery storage systems, and electric-vehicle chargers, on nearly equal footing with Tesla’s energy generation and storage division.
Tesla’s energy arm, widely celebrated by Wall Street, posted $12.77 billion in revenue last year on record deployments of 46.7 GWh. The two businesses share remarkably similar growth trajectories, yet they occupy vastly different positions in the public eye.
The disparity is partly structural. Huawei is unlisted, employee-owned, and its energy business represents just 8% of a wider group that booked 880.9 billion yuan in total revenue and 68 billion yuan in net profit last year. The company also does not break down the division’s product lines or profits.
More importantly, the West stopped paying attention. After being shut out of European and North American telecoms networks on national security grounds, Huawei was widely assumed to have shrunk. Instead, it pivoted sideways into the hardware layer of the energy transition, where the political temperature is lower and the margins are reliable.
Solar inverters are an ideal category for this quiet expansion. They are unglamorous, heavily standardised, and difficult to displace once installed. Crucially, they sit at the exact point where a solar array meets the grid, which is precisely where the most valuable operational data is generated.
While Huawei’s immediate growth is concentrated outside the West—driven by a new energy storage partnership in Brazil and expansion across Africa—the broader pattern carries deep implications for Europe. The continent is already heavily reliant on Chinese manufacturers for solar panels, going so far as to stockpile €7 billion of Chinese solar equipment in the name of energy security.
This dependency is becoming increasingly fraught. Beijing is actively wiring renewable generation directly into its data centres, while Europe is learning the hard way that artificial intelligence power loads and clean power do not automatically arrive in the same place. Denmark’s recent pause on grid connections underscores the physical bottlenecks facing the continent.
Huawei’s trajectory follows a familiar industrial playbook. By entering a hardware category that Western firms treat as low-margin plumbing, a Chinese company can capture volume, set standards, and lock in an installed base. The result is a stark reality for European policymakers: the unglamorous plumbing of the energy transition has become a strategic asset, and it is no longer in European hands.
